Methods to Estimate Surface Roughness Length for Offshore Wind Energy
Table 4
Statistical properties of surface roughness length during the CW Historical (2003–2007) and IMPOWR (2013-2014) campaigns at the Cape Wind tower obtained with the analytical, Charnock, and statistical methods. Note that the statistical method is not intended to give realistic values of surface roughness length, which are listed here in the last column just for completeness.
